Commissions, Rainy Days and Everything in Between

Commissions.  The next step in the evolutionary process of modeling, where one gets compensated for working on something one loves to do.

Even though I have had a few inquiries before, I haven't really done or have accepted commissions because at the time, circumstances prevented me from doing so.  I've had inquiries where I am asked to do repair work, but it was simple enough, I just told the one inquiring on how to fix it himself.  There were also at least major build commissions that came to my doorstep, but I had projects back then, both Gunpla and otherwise, so I wasn't able to do make a commitment.  There were also hints by people if I wanted to sell my previous builds, but all I can tell them was, "I'll think about it" and never followed through.

Raining Hell.  It was a rainy day.  Someone from Gundam Philippines, a local group of modelers and collectors, issued a challenge that was right up my alley and was too hard for me to resist.  The Challenge?  Convert a PG Wing Zero Custom to a DeathScythe Hell.  I wouldn't have noticed the thread, that group has very active members who constantly post almost anything under the sun aside from the usual stock of Gunpla and toy-related stuff, if not for the fact that I was tagged at least twice on that thread, and once tagged, I get all the notifications when someone posts after the tag.  I got at least 20 notifications on that post alone, and since I was at an off-site training at the time, the notifications I  got ballooned.

Coming Soon!

In one of my replies I said, "If this is serious, I'm in.  I'll need references."  I listed the DeathScythe as one of my top ten favorite mobile suits, so it was that more than anything else that made me accept the challenge.  I needed an excuse to get an MG DSH, and surely enough, I got one.  Aside from being my reference, I'll also me modifying the MG DSH to reflect what modifications I will put on the conversion.  Hence, the Hellraiser Project is born.

This is going to be enormous.  My thoughts linger on how I simplified my wing design and construction for the Bathala, but even that is still rather complicated because it is fully articulated in several places, compared to the that of the Deathscythe Hell's wings.  So, it wasn't a stretch that I didn't see the wing as a major thing to worry about, but, it would be the major part of the build since it'll be built entirely from scratch.

The Bathala's Wings
The MG Deathscythe Hell's Wings.

Even though Arvin Ignacio, the one who issued the challenged, and I haven't talked details yet, I was already thinking of how to improve the DSH's wing (I actually have been thinking about it since the MG DSH was released).  I'll modify the Wings as such there won't be any gaps when it is fully spread.  If I am able to do that on the MG, I'll be able to do it on the PG.  I won't be replicating the MG Wing point by point in internal construction because of the scale and like always, weight issues, but the functionality of the two will be similar.

I have leeway on making the PG DSH's wing more stable because it has a solid structure throughout.  I'll also tweak the design, making the the curves curvier and longer, to give it a more organic look.

Second Wind.  In the heat of it all, Bryan Mallorca, one of the people who hinted on having me do a commission (at the time, I thought he was just responding to my joke about him giving me a rare kit if I do a commission) followed through and asked me if I was willing to do it.  He mentioned two kits, and I chose The HGUC Stark Jegan to build as I please and turn it to a "MatX Custom."  He and I met that afternoon over Hungarian sausage (along with a friend of mine) and sealed the deal.  This commission, which I hereby tentatively dub the Hercules, and the Hellraiser are now intertwined.  I will work on the Hercules while modifications on the Hellraiser are curing, using the quick techniques I've developed while building the Bathala ang the Haribon.

A Third and a Fourth, and maybe a Fifth.  The adage, "when it rains, it pours," have more than once applied to me, and literally most of the time during rainy seasons.  I get more projects, more opportunities, more brushes with serendipity during the rainy season, when I often choose not to go out in the rain.  But, I don't see rain as a bad thing any more than one would see clouds in the sky as signs of rains to come.  I just go on my day as it is, even though rain, and the weather in general, affect me directly in more ways than one.

Those people who also hinted on having me do commissions have also finally formally asked, even if it was just hypothetical.  As such, there are a few things for me to look forward to.

Speaking of the Haribon, I haven't touched it, literally, for almost 2 weeks now because of work-related stuff, and it stands on top of my mousepad, eerily eyeing my every move with an almost accusing stare.  The Hellraiser Project will have to wait a month, as my dreams of the Haribon might turn into nightmares, like when I was building the Ronin for the second time.  This is something I need to have done, not because there is a deadline for a competition, but I plan to do more builds as well finish the ones I've started in as short a time as possible.

"BATHALA" - PMX-003 MG The O vMatX Part IX

Taking Flight!  Though I will still be working on the Bathala, this will be the final update of sorts for this project overall, mainly because I have work projects coming in, and I have to decide if I'll even enter this year's GBWC. I might use this improved wing for another kit instead of entering with the Bathala, mainly because it'll be too costly for me to get another MG The O at Toys R Us at mall price just to be able to enter. I'm thinking of getting an Infinite Justice or Sword Impulse (or some other similar kit), but as of the moment everything is frozen, even my budget for any new kit.

Anyways, I've finished majority of the wing, enough to be able to mount it and do a test fit to see if the mechanism can hold up to the weight. As predicted, the weight is rather significant, probably as heavy as the PG Strike Freedom's backpack/wing. The central gear mechanism is able to hold both wings when folded, or even when the main wing is spread, and so does the wing arm. I've made adjustments to the gears of the wing arms, pinning the gears on the receptacles aside from superglue, so that it holds it's place even during high tension. I've also added lock washers to prevent the nuts from slipping out when the wings are being handled.

The wings spread out. The main wings look short because of foreshortening especially since they curve inward. Looking at it at an angle reveals how long the longest "feather" really is (left wing), and how it curves inward (right wing).

Posted Image Posted Image

Test fit. The Bathala can actually hold the wings up on its own when the Main wings are folded inward towards its center of gravity. I've also added another pair of V-fins, these coming from my PG RFA.

Posted Image Posted Image Posted Image

The wings, "fully" spread. I can still spread it further but it would look unnatural. Because of the overall weight, plus, the added leverage when spread, I won't be able to do this kind of pose for the wing (unless I make pose receptacles for them), not that it will be allowed if I enter it in the GBWC this year. In this configuration, the wingspan comes to a kewl ~100cm (~39in). I had to lay this down on the floor and set my tripod up down angle to get the entire thing inside the viewfinder.

That's it for now. Will post another update if ever.

"BATHALA" - PMX-003 MG The O vMatX Part VII

A quick update:

As I previously assessed, overall weight is an issue when it comes to connecting the base of the wing to the back pack. Still, of all the mechanisms I imagined and tested (I even tested the swivel/hinge units of the extra sword arms underneath the front skirts), nothing could hold the combined weight of the wings. I began thinking of crazy mechanisms again, until the simplest solution became obvious.

A single pivot connection won't cut it, unless I use screws and nuts again, which I am avoiding because this is the very same thing that caused my problems with my previous wing designs. I also use a dual pivot system before with the Angelus, but it also failed because of inherent flaws in the design itself.

So, what if, I used a dual pivot system which has parallel connections?

Posted Image

The mechanism is so simple, with nothing more but a pair of sandwiched polycaps that are interconnected by two beams of equal length, working on the principle of a dynamic parallelogram to create angular motion.

Posted Image

Again, simplicity wins. Despite the weight of the wings, the simple mechanism holds it up. I will still need to reinforce this, disguising that as detail later on.

Posted Image

More (much) later. I have a couple of projects coming in, so I won't be able to work on this monstrosity for a couple of days or so.

"BATHALA" - PMX-003 MG The O vMatX Part VI

The Evolution of Design. As an all-around Graphic Designer for the last 20 years, I've seen design disciplines evolve with the times. In those two decades, I've learned that sometimes, if not most of the time, the simplest of designs is often the most effective, especially with logos or corporate identity.

This also holds true with industrial design, an in my case, Gunpla. I have been fascinated with most anything that has wings that, aside from weird and unique designs, I actually tend to lean on those that have wings, or at least, a semblance of it, with a few exceptions (I don't like the Destiny since its "wings" looks forced, and though I did get the MG Strike Freedom at a huge discount, I never really liked it either, not to say that what I'll do now would look okay later on). The designs I like so far are the Kyrios, the Zeta Plus A1, the Epyon and of course, the TV version of Gundam Wing.

I have made several attempts on wing designs, the simplest so far was what I've done for the Ice Queen. This was a "simple" swivel mechanism where the wings are attached on a single pivot point.

Posted Image

Before that was the Impaler Wings (for the MG Sinanju), my first attempt at a fully articulated and multi-joint wing design.

Posted Image Posted Image Posted Image

This was plagued with stability problems mainly because of its complicated design, with all the connective parts I tried to include. I abandoned it altogether and simply put it as learning experience (in my case what isn't?).

Then, there were the Angelus Wings, a "simplified" version of the Impaler Wings, but worked on a similar joint concept. Though it worked wonderfully, it was still unstable. Also, there were the Chimera Wings, which has a solid design, but failed while I was setting it up during the 2010 BMWKC. I was so frustrated back then, I already knew it wasn't going to win anything by the time I got home.

I realized then that any wing design that has multiple points of articulation with screws will have this problem, so I had to do radical rethink.


The Bathala Wings. This is a takeoff from the Angelus wing design, but I simplified it further by reducing the swivel point of the main wing design to one.  I've also added a lock nut to keep the swivel firm. I still wanted the main wing to spread and fold like a fan, but instead of using "gear points" which will limit how the wing spreads and will require holes and pegs located at certain angles (as with the Impaler), or actual gears to automate the wing spread or fold by pulling one out (the Angelus), I used what should have been most obvious from the start.

Instead of a single piece, each "feather" of the main wing is made of two pieces, cut and attached at a certain angle as such the lower layer "catches" the movement of the higher layer thereby creating a natural angle limiter between layers.

Posted Image

I made two prototypes, then decided to use the design of the larger one (keeping the prototype untouched, just in case) to match the Bathala's height. I then encased the joint portion with a simple "box" that follows the shape of the wing. The main wing's span is already at 29 cm, so this thing is going to be huge and heavy. I used all my remaining 1.0mm HIPS for these, since I noticed that even the 1.0mm tends to grow stiff and brittle over time.

Posted Image Posted Image Posted Image

Unlike in the Angelus, the Bathala has a lower compound wing with "feathers" that also fold in and out slightly. The feathers are compounded in a 4-3 configuration, each with its own articulation point.

Posted Image

A very "dry" test fit. This is how it should look like when the main and lower wings are attached.

Posted Image

Joining the Wings. Initially, I decided on a simple swivel mechanism to connect the main and lower wings, but that basically limited the Wing's swivel in one direction. I wanted the wing to swivel in several directions so that I can pose it folding over the shoulder of the Bathala somewhat, similar to that of the WingZC. I thought about this a lot, and the only way I can achieve this without making the joint too complicated was to use 8mm Revoltech Revolver ratchet joints. These joints are rare and very difficult to procure, and I got a few of these from R10 via M1Gs a couple of years back and haven't been able to use them, well, until now.

With the Bathala's wing becoming heavy, I had to make sure that that joint's pegs can handle the weight (they're thin and actually soft, being made with High Density Polyethylene, a plastic similar to polycaps), so I made peg modules by encapsulating polycaps with HIPS and WHIPS. These not only hold the polycaps but reinforce them as well. I'm still deciding if I'll mount them permanently on their respective sections or have them removable.

Addendum (18 July 2012):

Lightning update. Though it's main purpose is to hold the main wing up, the lower wing also has semi-articulated compound feathers that swivel out for a full spread pose. This combines weight support functionality with wing aesthetics, so if I was thinking the same way I did before this would be very complicated.

Instead, I drew inspiration from the main wing of a jumbo jet. The mini-wings will be encased in a wing-shaped "box," and that in turn is constructed in such a way that it it becomes solid in itself without additional reinforcement. The final assembly has potential to be very heavy, so I had to reduce weight by removing material inside the "box." This is easily hidden with the layered armor, in which I also removed material covered by the overlapping layer.

I worked on the connective modules of the joint between the main and lower wings I'm still struggling with OC tendencies to make everything removable. The 8mm Revolver joint holds the wing in place at that angle, but I would have to deal with it spinning somewhat on the "axis" of the peg because of the overall weight.

With this simple configuration, I was able to do the entire wing assembly in roughly 4-5 days, whereas, my previous (and somewhat failed) attempts took weeks, if not months, just figuring out the mechanisms.
